I start up my MC and it has worked many times before and now i click play and it loads and then it goes away and the launcher screen comes back up? I go to my Development Console and the only Error i get is this

ERROR]: Game ended with bad state (exit code 1)
then takes me to the [game output] tab and says

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/logging/log4j/LogManager
